The following specification describes the invention and the manner in which it is to be performed.
TECHNICAL FIELD
The present subject matter described herein, in general, relates fluid dispensers. More particularly, the present subject matter relates to a detachable plug with a nozzle for dispensing fluid.
BACKGROUND
The plugs with a nozzle are fitted on a container such as bottle of tube for dispensing fluid through a nozzle. These nozzles dispense the fluid even without applying any pressure if the mouth of the nozzle has a wider diameter. For these reasons, the mouth of the nozzle is kept small. Problem with such nozzles is that they dispense un-even amount of fluid, which many leads to wastage due to dispensation of extra fluid than required. Further, the nozzles available in the art work on a principal of differential pressure conditions. The traditionally available nozzles do not work well in the low-pressure conditions.
Thus, in order to dispense fluid of precise volume, a pipette is used. However, the pipette has limitations in terms of ease of usage and require constant refilling. In other words, there are no equipment available in the art that can be installed directly on a container and can ensure dispensing of fixed volume of droplet from a container. Thus, there is a long-standing need of a plug with such a nozzle that is able to dispense same amount of fluid on applying the pressure on the container.
Thus, there is a long-standing need of a plug with a nozzle that solves above-mentioned problems. There is also a need for a detachable plug with a nozzle that can be used in low pressure conditions.
